Hello!

You simply divide 78 by 171.

78÷171= 0.45614035

Rounded: 0.46

78 goes into 171 two times. This is because all you have to do is divide 171 and 78 and get 2.192307692. 78 goes into 171 two whole times. Hope this helps you.

The point (0,-5) is not located in Quadrant IV because it has a negative y-coordinate.

The point (0,-5) is not located in Quadrant IV because Quadrant IV is the bottom-right quadrant of the coordinate plane, where both the x-coordinate and the y-coordinate are positive. In Quadrant IV, the x-coordinate is positive and the y-coordinate is negative. A coordinate point with a negative y-coordinate would be located in Quadrants III or IV.

I’ve had this question back when i was in school.

You have to calculate at regular price.

4 x 9.75 = 39

Subtraction time. 10 people are renting, 4 are members  

10 - 4 = 6

6 that are nonmembers. 4 members  

6 x 3.95 = 23.70

4 x 2.95 = 11.80

Add all those up.

39 + 11.80 + 23.70 = 50.80 + 23.70 = 74.50

Answer: $74.50 :)

Answer:

Average decrease in car's value per year = 1800$

Explanation:

  The worth of car bought by Mr. Solan = 30000$

  Reduction of car's price = 5400$

  Number of years considered for measuring reduction of car's price = 3 years.

  Average of values = Total of the values/ Number of values.

  Average reduction per year = Total reduction/ Number of years.

                                                 = 5400/3 = 1800$

  So average decrease in car's value per year = 1800$

The equation which has no solution is:

                           Option: C

           c)     [tex]7y+9=7y-6[/tex]    

The equation is said to have a no solution if we get a false identity on solving the equation.

a)

[tex]5m-6=5m+7-m[/tex]

On combining the like terms in the right hand side of the equation we have:

[tex]5m-6=5m-m+7\\\\5m-6=4m+7\\\\5m-4m=7+6\\\\m=13[/tex]

Hence, we get a unique solution to the equation.

b)

[tex]3w+4-w=5w-2(2w-2)[/tex]

on using the distributive property in the right hand side of the equation we have:

[tex]3w+4-w=5w-2\times w-2\times (-2)\\\\3w-w+4=5w-2w+4\\\\2w+4=3w+4\\\\3w-2w=4-4\\\\w=0[/tex]

Again we get a unique solution to the equation.

c)

[tex]7y+9=7y-6[/tex]

on subtracting 7y from both the sides of the equation we have:

[tex]7y-7y-6=9\\\\-6=9[/tex]

which is a false identity.

Hence, the equation has no solution.

d)

[tex]4z+8=-4z-2\\\\i.e.\\\\4z+4z=-2-8\\\\8z=-10\\\\z=\dfrac{-10}{8}\\\\z=\dfrac{-5}{4}[/tex]

This equation has a unique solution.

1. If the product of these integers is to be 1, then all of them must be either 1 or -1.

2. Since the product is positive (+1), it must be that there are an *even* number of negative ones (-1), if any.

3. If the sum were 0 it would mean that the number of +1's must equal the number of -1's. So that means there would have to be exactly 22/2=11 of each.

4. But if there were 11 of each, that means the number of -1's would be *odd* and there's no way the product could be +1 (as stated in 2 above).

Hence, the sum is never 0, if the product of 22 integers is equal +1.

Fun problem.

We have a positive product, so no zero factors.

We have a positive product, so an even number of negative factors.

We have a product of 1, so all the integers must be either +1 or -1.

If we have 2n factors of -1 we have 22-2n factors of 1 so a sum of

[tex]s = (-1)2n + (1)(22-2n) = 22-4n[/tex]

For that to be zero we need

[tex]0 = 22-4n[/tex]

[tex]n = 22/4 = 11/2[/tex]

That's not an integer; we've shown there's no even number of -1s that will make the sum zero, and since there must be an even number of -1s, the sum cannot equal zero.

Final answer:

The x-intercept of the graph 2(y+0.5) = 3.5x + 2y is 2/7, and the y-intercept is 0.5.

Explanation:

To find the x and y intercepts of the graph of the equation 2(y+0.5) = 3.5x + 2y, we first simplify the equation. Start by distributing the 2 on the left side:
2y + 1 = 3.5x + 2y. Next, subtract 2y from both sides to get:
1 = 3.5x. Now, to find the x-intercept, set y to zero and solve for x:

x-intercept: y = 0
1 = 3.5x
x = 1 / 3.5
x = 2/7

To find the y-intercept, set x to zero and solve for y:

y-intercept: x = 0
1 = 2y
y = 1 / 2
y = 0.5

The x-intercept is 2/7, and the y-intercept is 0.5.

Answer:

A total of 72 passenger planes came in yesterday.

Explanation:

  Blue Sky International Airport handles passenger to cargo traffic in a ratio of 8 to 5.

  Number of cargo planes landed yesterday = 45

  Number of passenger planes landed = [tex]\frac{8}{5}[/tex] x  Number of cargo planes landed.

 Number of passenger planes landed yesterday = [tex]\frac{8}{5}[/tex] x 45

                                                                               = 8 x 9

                                                                               = 72 passenger planes.

 So a total of 72 passenger planes came in yesterday.

Final answer:

To find the length of the shadow cast by a 35-foot building with a 60° angle of elevation to the sun, we can use trigonometry. The shadow is approximately 60.6 feet long.

Explanation:

To find the length of the shadow, we can use the concept of trigonometry. In a right triangle, the opposite side is proportional to the shadow length and the adjacent side is proportional to the height of the building. Using the angle of elevation of 60° and the height of the building as 35 feet, we can set up the trigonometric equation as follows:

tan(60°) = x/35

Solving for x, we get x = 35 * tan(60°) = 60.6 feet. Therefore, the shadow is approximately 60.6 feet long to the nearest tenth of a foot.

The 2 points closest to the line is (4,12) and (20, 36)

The slope is the change in Y over the change in x:

Slope = (36-12) / (20-4)

Slope = 24 / 16

Slope = 1.5

So now you have y = 1.5x

To find the equation use the formula (y-y1) = m*(x-x1)

y-12 = 1.5(x-4)

Simplify the right side:

y-12 = 1.5x - 6

Add 12 to each side:

y = 1.5x +6

The answer is the 2nd one.

The given quadratic equation y=x^2+4x+5 has no real solutions because the discriminant is negative. Therefore, there are no zeros for this equation, making option A (There are no zeros) the correct choice.

The question asks to identify any zeros of the quadratic equation [tex]y=x^2+4x+5.[/tex]To find the zeros, we need to set the equation equal to zero and solve for x. This is typically done using the quadratic formula, which is √x=(-b±√(b^2-4ac))/(2a), where a=1, b=4, and c=5 in our equation.

Substituting these values into the quadratic formula gives: x=(-4±√((4)^2-4*1*5))/(2*1) = (-4±√(16-20))/2 = (-4±√(-4))/2. Since the value under the square root sign (the discriminant) is negative, this equation has no real solutions. Thus, there are no zeros for the given quadratic equation, making option A the correct choice.

To evaluate a function at a specific x value simply means to substitute that particular value in place of every occurrence of the variable x.

Answer: There are 12 greatest number of arrangements that she can make and every balloon is used.

Step-by-step explanation:

Since we have given that

Number of white balloons = 24

Number of blue balloons = 60

We need to find the greatest number of arrangements that she can make and every balloon is used.

So, For greatest number of arrangements we will find H.C.F.

So, H.C.F. of 24 and 60 = 12.

Hence, there are 12 greatest number of arrangements that she can make and every balloon is used.
